Abstract
Description
- The present invention relates to a multipolar plug connector for establishing contact with a multilayer board as defined in the preamble of the independent claim.
- DE 699 15 882 T2 describes a plug connector suited for high-frequency data transmission. Each signal contact element is assigned a screen or mass contact element. The orientation of the contact elements is selected so as to allow impedance matching.
- U.S. Pat. No. 6,976,886 B2 describes a plug connector by which a high screening effect between the signal lines one relative to the other, and of the plug connector generally is to be achieved, by a special arrangement and/or orientation of the signal and screen contact elements one relative to the other. The known plug connector is especially well suited for high-frequency signals, and in addition the arrangement of the signal and mass contact elements is especially defined so that a specific surge impedance is provided.
- The multipolar high-frequency plug connection described by DE 39 36 466 A1 comprises a plug connector having a metallic screen that is connected with two contact elements intended for contact-making with a circuit board. The two mass contact elements are arranged on both outer surfaces of the plug connector. The screen is not especially assigned to a selected signal contact element.
- DE 29 49 013 A2 describes a frequency-optimized connector between a coaxial cable and a circuit board. The neutral conductor of one coaxial cable is connected with a strip conductor arranged on a board. Screening of the coaxial cable results in a mass surface which, in the area of the signal strip conductor, is subdivided into two mass conductor strips arranged adjacent to the signal conductor strip. At the other end of the board, a multipolar plug connector is fixed on the board by soldering. A plug connector contact element is soldered to the signal strip conductors. At the side of the signal contact element four neighboring contact elements are soldered to the mass surface of the strip conductor arrangement.
- DE 39 04 461 C1 and DE 39 36 466 A1 describe multipolar high-frequency plug connectors where at least one of the corresponding plug connectors comprises a metallic screen connected with two contact elements intended for establishing contact with a circuit board. The two mass contact elements are arranged on both outer surfaces of the plug connector.
- DE 198 07 713 A1 describes a plug connector comprising a large number of contact elements. The known plug connector is intended to establish plug connections between backplanes and plug-in cards of what is known as compact PCI systems.
- Now, it is the object of the present invention to provide a plug connector for establishing contact with a multilayer board, in combination with a multilayer board, which together allow efficient screening up to the upper high frequency range.
- This object is achieved by the features defined in the independent claim.
- The multipolar plug connector for establishing contact with a multilayer board, which comprises signal contacts that are assigned a first and at least one second screen contact element and are arranged adjacent to the signal contact, distinguishes itself by the fact that recesses are provided at least on the upper layer of the multilayer board which are suitably sized so as to receive and lead through at least two screen contact elements assigned to neighboring signal contacts.
- It was found by simulation that distributing the screening to at least two screen contact elements assigned to one signal contact considerably improves the screen rate compared with a single screen contact element. In order to adapt the multilayer board to a plug connector, the multilayer board is provided with through-holes that are properly sized to receive and to lead through the at least two screen contact elements.
- Further, by assigning at least two screen contact elements to each of the signal contacts, uniform local inductivity is achieved within the plug connector, and within the multilayer board as well. Correspondingly, the characteristic or surge impedance is homogeneously distributed within the plug connector and within the multilayer board.
- Due to that arrangement, the plug connector, in combination with the multilayer board equipped with the plug connector, is generally suited for carrying signal frequencies up to the upper GHz range. The simulation results could be confirmed by experiments.
- Advantageous embodiments and further developments of the plug connector according to invention for establishing contact to a multilayer board, in combination with an especially designed multilayer board, are apparent from the dependent claims.
- One embodiment provides that the signal contact which is screened by at least two screen contact elements comprises a pair of signal contact elements which, according to a further development of that embodiment, are suitably connected for carrying differential signals.
- Another embodiment provides that an electrically conductive screening ring is provided at least in the area of the rear outlet of the contact elements from the plug connector housing, which ring encloses, at least in part, the signal contact to be screened. That feature is suitable to improve the screening effect especially when the screening ring is in contact with the first and the second screen contact element, as provided by a further development of that embodiment. According to another further development of that embodiment, a plurality of screening rings may be connected one with the other.
- One embodiment provides that the screen contact elements assigned to one signal contact, as well the at least one signal contact element of the signal contact, are arranged one beside the other in a row and/or a column of the plug connector, at least approximately. The uniform geometric arrangement increases the homogeneity of the surge impedance within the plug connector, including the multilayer board equipped with the plug connector.
- According to another embodiment, the screen contact elements are in contact with mass surfaces provided on one or more layers of the multilayer board, in which case the mass surfaces may be subdivided into a plurality of partial areas in order to influence the screening effect and/or the surge impedance as required.
- A preferred use of the plug connector with the multilayer board provided for contact-making provides for the use of the multilayer board as a backplane. Details in this respect can be derived from the cited prior art as known from DE 198 07 713 A1.
- A further development provides that the plug connector is assembled from segments that contain the signal contacts and screen contact elements arranged in a row or column one beside the other. The different segments may comprise a screening sheet at least on one side. Those features allow easy production of the plug connector.
- Another further development provides that the multilayer board comprises at least a single continuous recess intended to receive and to lead through a pair of signal contact elements. Production of the multilayer board is rendered especially easy if instead of certain individual recesses intended to receive and to lead through each pair of signal contact elements, such receiving and lead-through recesses are provided for every pair of signal contact elements.
- Other advantageous further developments and embodiments of the plug connector provided for establishing contact with the multilayer board, including the multilayer board, may be derived from the embodiments described in the following, and from the drawings.
